Just read this in your other thread:

[QUOTE=whiterabbitrexy;827824]Hi guys i wana do a engine block flush not a radiator flush on my 1998 wrx impreza gc8 ej20 turbo engine ....well I will do I radiator flush but I want to focus mainly on a block flush because of my turbo is letting oil residual sludge in my coolant system. [/QUOTE]

Seem like you have much bigger issues to deal with before you Waste your money on making the car go harder.

[QUOTE=Rossco;827848]The only speed limited factory GC8 ecu's are the V5 & V6 STI ecu's which speed limit at 180kph.

Unless you motor has been rebuilt with some 'goodies' in it that GTX turbo is going to suck ass on a stock EJ20T.

I don't know why you've settled on a turbo with a 3" inlet anyhow - are you going for a rotated turbo mount??

You need to find yourself a tuner, buy a decent ECU & heed your chosen tuners advice before you waste your money on a combination of parts that won't work well together.

'High boost' on a stock ECu is 16-17 Psi.......... High boost for me is 25psi+[/QUOTE]

Engine has had rebuilt bottom end with 03 sti internals crank/rod/pistons... But I'm pretty sure it has stock heads on it.... It's not a rotated turbo mount just a normal stock bend induction...

Reason I have changed my stock turbo inlet is because the stock one is melted at the turbo housing and why go oem why I can get a better one for cheaper prices and later down in the future I have a 3inch inlet for better airflow instead of the 2inch turbo inlet

I did a head gasket on it and was still slowly droping oil/ wired sludge into my coolant...
I gave it to a mechanic to do another head gasket with arp head bolts and oem 3 layer metal gasket type and still the same deal with the coolant..... Now only thing to do is to change my turbo because my old Vf22 has sacked in something in and bent the turbine fins/blades and turbo seal is completely gone as to smoking up pretty bad on start up and on boost it smokes...it's not my value seals I've done them....

Now once I change my turbo to a new turbo If i still get oil in my coolant then I know my block is on its way and I don't care about the block any more can't keep trying to fix something that I don't know how to fix instead just getting a new bare block for 1.5k and start from there....because it's not the heads they have been crack pressure tested

Stock 03 STI rods and pistons are far from goodies mate . As others have said find a reputable tuner and talk about what you're trying to achieve. Not trying to be a kunt , but you're knowledge is very limited and sounds like you have either been told misinformation, or read it on the interwebs .

Before making a costly mistake talk to a workshop or tuner with experience and come up with a build plan to achieve your goals .

Just slapping a big turbo on and assuming you have supporting mods won't get you anywhere but broke. Just so you know you can have stock injectors or 550 or 1200 cc the fuel pump will sound exactly the same .
